To all whom 27m/ay concern,.-

Be it known that I, ANDREW STARK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois haveinvented certain new and useful Improvements in Grain-Binders, which are fully described in the following specification.

This invention is an improvement upon the knot-forming mechanism of a grain-binder, and relates particularly to the cord-holder.

It consists of a cylindrical cord-holding ring revolved about the knotter-bill, having notches in one edge to receive and carry the cord intoA proper position to be seized by the knotterbill, and by the same motion carrying the cord to a suitable clamp cooperating with-the said ring to hold the ends of the cord.

In the drawings, Figure 1 is a rear elevation. Fig. 2 is a front elevation. Fig. 3 is an inner` side elevatiom Fig. 4 is a sectional plan of the parts below the plane x x on Fig.' l. Figs. 5, 6, 7 8, and 9 are detail views showing successive positions of the' knotter bill relative to the breast-plate and to the cordholder. Fig. 10 is a detail plan of the mutilated pinion that drives the holder-ring. Fig. l1 is a front elevation showing the relative positions of the neeldle and the knotter-actuating wheel. Fig. 12 is a partly-sectional plan of the knotter-frame and breast-plate, showing how they are fastened together. Fig. 13 is a sectional elevation of theinside ofthe cord-holder ring and cord-clamp, section being taken on the line LU w, Fig. l2.

Ais the binder-frame. Bis the breast-plate. C is the needle. C is the 'needle rock-shaft.

' D is the mainv shaft of the binder. E is the ward therefrom. The frame H is secured to the breast-plateBby the bolts 71J andh, through the iiange H4. `It has also the brace orhanger' H5, secured to it by the bolt h2, and to the breast-plate B by the bolt h3. The knetterbill vI is actuated in the usual manner by the gear-segment E on the knotteractuating wheel E. The breast-plate B has the usual slot, b, for the needle to pass and carry the cord to the knotter; but the form ofthe slot is such asV to produce the tongue B,-standing transversely across the general direction of the slot b, and terminating directly below the knotter-bill shaft il, and having the obliquelycurved edge Zi on the inner side. f

K is the cord-holder ring. Itis an open ring, being in effect a short cylinder having the equidistant notches k on its upper edge and the bevel-gear rim K on its outer surface at the lower edge. It encircles the knotterbill I, its axis being preferably about parallel to that of the knotter-bill and being inclined upward on the inner side-the side from which the needle advances toward the bundle-and being sustained upon the shoulders h5, h6, and h7 of the frame H, the first being on the brace or hanger H5. It is placed in position on the shoulders h and hl'before the brace H5 is put into place, and before the breast-plate Bis fastened to the frame H. The braceor hanger H5 being put into place, with its shoulder h5 under the rim of the ring, secures it, and on the three bearings it is revolved by means of the bevelpinion L, meshing with the bevel-gear rim K. Said pinion L is fixed on one end of the shaft Z, which is journaled in the bearings hs and hg on the frame H, and carried by the bevel-pinion L', on its upper end meshing with the gearsegmentEz on the knetter-actuating wheel E.

- The pinion L has two delay-surfaces, Z, di-

rectly opposite each other. Said delay-surfaces co-operate with the delay-surface e on the knotter-actuating wheel E, to lioldthe pinion and its shaft and the cord-holder ring.

small part of the revolution of the knotteractuating wheel, and the pinion L and shaft Z and pinion L make but li-.ilf a revolution for each full revolution of the knotter-actuating wheel. The pinion L, by such half-revolution, is adapted to rotate .the ring K the distance from notch to notch.

' By placing the axis of the knotter-bill laterally oblique to the plane in which lie the axes of the knotter-actuating wheel and the needle it is made possible to place the cordholder ring at right angles to the knotter-bill axis, as described, so that the jaws revolve in cords position, when the knotter seizes it, is

determined, as nearly as possible in line with the axis of the bill, thereby reducing to the minimum the length of cord intervening between the bundle and the knot-that is to say, facilitating tying close to the bundle.

If the axis of the bill were located, as usual, in the plane in which are located the axes of the needle and knotter-actuating wheel, the result above set forth could be attained only by greatly enlarging the ring K, thereby sacricing coinpactness or changing the direction of the plane of the ring K, and sacrificing the advantage of that direction.

M is the cord-clamp block. It is secured by the screw or bolt m to the frame H, located outward from the knotter-bill and on the same side ofthe path of the needle as said bill. From its said point of fastening it extends for about ninety degrees around the bill in a curve agreeing with that of the ring K. It is preferably in the form of a clasp or saddle striding the rim K1, though it may be made to bear only on the outside of that rim. The inside wing of said clamp-block has the notch m to guide the cord, as hereinafter explained. In addition to the fastening by the bolt m, the clamp block M is rendered more rigid by means of the spur hl'?, jutting out from theframe H and forming a stop or brace for the clamp-block above the end farthest from the bolt m. The end adjacent to the path of the needle has the projection or spur m2 to guide the cord.

N is the cord-cutter. VIt is a knife or chisel fastened to the free end of the spring or yielding arm N', which is secured in place by the bolt h', which passes through the lug H* of the knotter-frame to secure it to the breast-plate. Said cutter and its spring-arm are, therefore, wholly within the ring K. The cutting-edge n has preferably the V-shaped notch n opening downward and adapted to stride the cord, and so sever it more easily than could be done by the direct stroke of a straight cutting-edge.

The cutter is forced down upon the cord in proper time by the cam E5, fixed on the front face of the knotter-actuating wheel E in position to impinge upon the upper sloping por` tion, N, ofthe yielding arm N It is retracted by the reaction of said spring or yielding arm N after the cam E5 has passed it.

rlhe action ofthe above-described mechanism is as follows: At starting, the end of the cord is secured in the holder by being grasped between the rim K2 and the outer flange or wing of the clamp-block M, whence the cord passes through one of the notches k, and back over the tongue B of the breast-plate B, to the eye of the needle. When the needle rises and carries the cord around the bundle, it passes through the slot b in the breast-plate B and enters the ring K from below', near the inner edge, passes through it and overh angs its outer edge. (See Figs. l and 4.) In this process the running cord is carried through the slot-b, and meeting the transverse tongue B is laid across it, and thence extends alongside the fastened endof the cord into the notch k. (See Fig. 5.) The slope ofthe tongue B' on its inner side, b', tends to cause the cords lying across it to slide toward the shank of the knotter-bill as the cord is tightened around the bundle. The

knotterbill `at this stage stands at rest in the position shown in Figs. 5 and 1, pointing obliquelyp outward and downward toward the plane of the cord, and with its point a little lower than the cord asit runs from the tongue B to the notch k. (See Fig. l.) At this stage the gearsegment E on the knotter-actuating wheel E engages the pinion L and the ring Kis revolved one-eighth of a revolution in the direction of the arrow-head on Fig. 5, carrying the double cord which lies in the notch k toward the knetter-bill shank and into the clamp, and stops, leaving the cord running from the tongue B', over the closed jaws of the knotter-bill I, into the clamp. Meanwhile the knotter-bill has started, the gear-segment E having come into engagement vwith the pinion I, and vthe knotter-bill shaft being inclined so that it forms an acute angle, with the cord on the side toward the holder, the cord being stretched from the tongue B to the clamp, and the bill or jaws be` ing about at right angles'to the said axis, the

revolution of the bill carries the jaws upward behind the cord and gathers the latter into the IOO angle between the shank and the bill, and when the bill has completed one-eighth of its revolution thevposition of the said bill', holder, and cord is as show-n in Fig. 6, the relation of the bill 'to the cordhaving changed ninety degrees, the cord having been carried by the holder forty-five degrees toward the hill, and the bill having revolved forty-five degrees toward the cord. The bill now continuing its revolution, the jaws are opened by the engagement, in the usual manner, of the roll i with the cam J, and so remain until the bill reaches a position at two hundred and seventy degrees from the startingponteen in Fig. 7),where it encoun-4 ters the cord ends between the clamp and the knotter-bill shank and receives them between its open jaws. The cords are at this point stretched tightfrom the clamp to the point where they are laid' across the bill, and their exact position in the path of the open knotterjawsisinsured by the notch m on theinnerwing of the clamp-block M, the cords having been guided by the sloping under edge of theinner IIO wing of the clamp and by the sloping sides of `be seen" that the cord needed to encircle the knotter-jaws may be drawn from the portion of cord surrounding the bundle, but at this stage, the cord being crossed on the knotter bill and drawn tight, no more cord can be drawn from that source; also that in the furby the revolution of the knotter-bill away from the clamp. The bill while thus closing revclves f to the position shown in Fig. 8, where it is fully closed. As it continues its revolution from this point, tightening the cord between it and the clamp, the cam E5 on the wheel E engages and depresses the cutter, and its notch n, striding the taut cords, severs' them between the clamp and the bill. The knotter comes to rest in the position shown in Fig. 9, which was the initial position. 'Meanwhile the knotteractuatingwheel E, continuingitsrevolution,the continued pressure of the discharger F against the bundle pulls the ends of the cord out from the jaws of the knotter-bill, and the` tying is completed. Meanwhile, the needle retiring fcarries the running cord back through the next notch c of the ring K down over the tongue B', and leaves the cord, as at starting, ready for a new bundle, and all partscome to rest in the initial position. l

I do not connue myself to the use of the holder of the construction described in connection with a knot-tying billor hook of the form illustrated; but said holder may be used' vin connection with any of the forms4 of knottying bills now in use; and I do not intend to be understood by the word bill77 to indicate merely such devices as have a vibrating jaw, but I include under that term any loop-forming device in a knotter.

The construction of the breast-plate having tongue B protruding across the needle-slot and terminating in line with the knotter-bill shaft, and the construction which causes the knotter to carry the cord around the end of said tongue, and the form of theouter portion of the slot, as shown in the drawings, are not claimed herein, because I have claimed said features of construction in my application No. 205,050, filed .Tune 14, 1886, which is a division of this application.
